CAL Digital Thermostats & Defrost Thermostats

Thermostat and Defrost Thermostat Devices

The CAL family of thermostats provides a range of options for basic heating and cooling applications.

The compact thermostats are quick to install. The simple menu option makes them extremely quick and easy to set up. Users also benefit from a large, clear display which provides good visibility.

Defrost Thermostat

The EDT defrost thermostats offer additional functionality to provide more sophisticated control of refrigeration systems such as compressor protection, defrost control, a real time clock and communications.

The EDT defrost thermostats also include a special CAL-Key which is designed to save time on programming. A configuration can be uploaded to the key allowing settings to be easily cloned across multiple devices. The CAL-Key is battery operated enabling thermostat units to be configured even when not powered up.
